Scientists create artificial sperm.

Can they artificially flavor it? From Daily Mail:

In a world first, British scientists have grown human sperm in the laboratory.

The breakthrough in stem cell science offers a potential cure for male infertility and could be used in IVF clinics in as little as five years.

It would allow thousands of men to father children that are genetically their own, possibly from just a sliver of their skin.

But the cutting-edge work is fraught with medical and ethical problems.

It raises the possibility of babies being born entirely through artificial means, and even the macabre scenario of long-dead men 'fathering' children from beyond the grave.
